Shutdown Corner

Lost a bit in the hoopla of the Philadelphia Eagles trading quarterbacks this offseason was that the quarterback they acquired was coming off back-to-back major knee injuries.

It appears, however, that Sam Bradford has had a successful rehab. Bradford, who suffered a season-ending ACL injury during the 2013 season and suffered another torn ACL in the preseason last year, practiced on Sunday when the Eagles opened camp.

McLane also wrote that Bradford has ditched a bulky knee brace in favor of a sleeve. Bradford told reporters the big brace was too constricting. He looks to be on track to start the Eagles' preseason opener, on Aug. 16.

Chip Kelly might be a bit crazy when it comes to personnel moves, but that doesn't make the Philadelphia Eagles coach a racist, no matter how hard people pitch that controversy.

Running back LeSean McCoy was first to insinuate Kelly was racist, likely because he was hurt he was traded to the Buffalo Bills. Former Eagles lineman Tra Thomasjoined in the chorus for some reason. Now the comments of cornerback Brandon Boykin, after he was traded to the Pittsburgh Steelers on Saturday, are being put under the "is Kelly really a racist?" microscope. Ugh.

The Pro Football Hall of Fame's Class of 2015 gets inducted on Saturday. Shutdown Corner will profile the eight new Hall of Famers over the next week looking at each of their careers and their impact on the game.

Will Shields Kansas City Chiefs, 1993-2006 Guard

Greatest moment

Shields will forever be known as a Chief, with his dedication to the team for 14 years, and among one of the best guards to ever play. He started 223 consecutive games and went to 12 Pro Bowls.

In a career highlighted by paving routes for running backs, perhaps his best feat is helping anchor a line that in 1994 yielded 19 sacks, a team record for fewest in a season. That year was Joe Montana's final season in the NFL.

Impact on the game

Shields was the third-round, 74th overall pick of the Kansas City Chiefs in the 1993 draft. His first start was the second game of that season, Sept. 12 against the Houston Oilers. In that rookie season, Shields made an immediate impact, leading the Chiefs to their first division title since 1971. He would become a bedrock in the Chiefs' starting lineup.

There are many, many problems with the way the NFL handled deflate-gate, and one is pretty basic: The league never cared about the air pressure of footballs before hammering the New England Patriots.

That was clear from the Wells report, when it came to light that the Indianapolis Colts told the NFL before the AFC championship game that they were concerned about the Patriots deflating footballs, and the NFL did absolutely nothing about it until it was brought to their attention again in the first half. If the inflation level of footballs was Absolutely Crucial To The Integrity Of The Game, they'd have done something other than shrug once they were notified.

Shutdown Corner is previewing all 32 teams as we get ready for the NFL season, counting down the teams one per day in reverse order of our initial 2015 power rankings. No. 1 will be revealed on Aug. 8, the day before the preseason begins with the Hall of Fame Game in Canton.

NO. 7: BALTIMORE RAVENS

In this offseason of regret, most of the focus has been on the Green Bay Packers and Seattle Seahawks, who blew playoff games in heartbreaking fashion. But don't forget about the Baltimore Ravens.

The Ravens didn't flub an onside kick or throw an interception when they should have been running from the 1-yard line, but that doesn't lessen their pain. Twice they held a 14-point lead over the New England Patriots in a divisional playoff game. The Patriots played incredible football down the stretch to barely pull off the win. Two games later, the Patriots won a Super Bowl.

The Ravens had to feel like that could have easily been them on the stage accepting another Lombardi Trophy.

The Pro Football Hall of Fame has reversed field and allowed Sydney Seau to speak at the induction ceremony of her father, the late Junior Seau, after initially saying she could not, according to Fox Sports' Alex Marvez.

The Hall had passed a bylaw in 2010, which prohibited a substitute speaker, such as a family member, for a deceased player being enshrined. Former Los Angeles Rams inductee Les Richter was the first posthumous member to be elected, and his family did not speak on his behalf — something they were fine with.

The Pro Football Hall of Fame’s Class of 2015 gets inducted on Aug. 8. Shutdown Corner will profile the eight new Hall of Famers, looking at each of their careers and their impact on the game.

Mick Tingelhoff Minnesota Vikings (1962-1978) Center

Greatest moment

Tingelhoff signed with the Vikings as a free agent after a distinguished career at the University of Nebraska at center. Tingelhoff won the starting job at center during his rookie year and never gave it up until he retired – 17 years later.

Perhaps Tingelhoff's greatest trait was his durability, never missing a game in a career that had 240 of them. He anchored a line that protected NFL legend Fran Tarkenton, allowing the famed quarterback to, at the time, set the all-time record for passing yards. He was also a great run blocker, paving the way for Chuck Foreman to string together three consecutive 1,000-yard seasons between 1975 and 1977.

A Cowboys fan set up a GoFundMe page to raise money to fly a banner over Eagles practice on Aug. 9 that read “ WE GOT THE DIVISION ” according to the Fort Worth Star-Telegram. That was in response to a rumor that Eagles fans planned to fly a banner over Cowboys practice reading "WE GOT DEMARCO," as in former Cowboys running back DeMarco Murray, who joined Philadelphia this offseason.

And the Cowboys fans got a pretty nice donation after asking Hardy if he wanted to kick in. Hardy's Twitter handle is said to be @OverlordKraken, though he hasn't gotten it verified. He gave $300 and posted a picture of the verification.

NO. 8: DALLAS COWBOYS

In a long-ago era, like maybe seven or eight years ago, we wouldn't be having this conversation about the Dallas Cowboys and their running backs.

The Dallas Cowboys would have re-signed DeMarco Murray, because running backs were not yet thought of as disposable quantities that you draft, use up and discard. In many ways, NFL teams have gotten smarter about investing resources in running backs. The return is often poor. But the Cowboys are taking that theory to the extreme.

The Cowboys reportedly made a good but not great offer to Murray, and Murray unsurprisingly walked. He signed with the Philadelphia Eagles. That isn't an insignificant loss. Murray was clearly the MVP of the Cowboys' 12-4 NFC East championship season in 2014.
